Our kitchen is older with just painted walls. I wanted something to make it look a little more modern and these did the trick! They look fantastic. It cost about $415 to do our entire kitchen but I think it was worth it. They are fairly easy to install but you need to be careful because once it partially sticks to something there is no going back. We have a few spots (that only I notice) where the "grout" is a little wider than in other areas.
